ALBERT L. ROSEMOND, OF OBERLIN, OHIO.

SPECIFICATION forming part of Letters Patent No. 722,907, dated March 17, 1903.'

Application filed August 28] 1902.

To all whom it may concern:

Be it known that I, ALBERT L. ROSEMOND, a citizen of the United States, residing at Oberlin, in the county of Lorain and State of Ohio, have invented anew and useful Rail-' Joint, of which the following is a specification.

Thisinvention relates to railway-rail joints and has for its object the production of a device wherein the size of the rail is increased opposite the portions forming the joint to not only strengthen, the joint, but also preventing the concussion from the passing trains deflecting the rails at the joints, and also relieving the tie-bolts from all shearing strains.

The invention consists in certain novel features of the construction,as hereinafter shown and described, and specified in the claims.

In the drawings illustrative of the invention, Figure 1 is a perspective view of one of the improved joints complete. Figs. 2 and 3 are perspective views of the adjacent ends of the rails disconnected. Fig. 4 is a transverse section through one of the tie-bolts. Fig. 5 is a bottom plan view.

The body portions of the rails areof the usual construction, consisting of the head flanges 10, the vertical webs 11, and the tieflanges 12, as shown. The head-flanges 10 are adapted to engage endwise, as illustrated in Fig. 1, and the vertical webs are extended in the form of overlapping tongues 13 14, the inner faces of the tongues arranged in vertical alinement with the centers of the vertical webs 11 and extended laterally, so that. the tongue portions are thickerthan the ver-' tical webs, of which they are continuations. The tongue portions extend beneath the outer portions of the head-flanges, and the vertical webs are formed at the roots of the tongues with shoulders 15, against which-- the ends 16 17 of the respective tongues abut when the rails are united, as indicated in Fig. 1. Adj acent to the shoulders thevertical webs are extended outward, as at 16, to correspond with the lateral extensions of the tongues 13 14, so that the outer surfaces of the tongues are graduallymerged into the general surfaces of the webs.

The tie-flange 12 is divided centrally oppo- S'erial No. 121,372. (No modeLl site the 'tongue portions 13 14, asindicated at 18 in Fig. 5, and with the ends rounded, ,as at 20 19, and adapted to'overlap,'as shown in Fig. 5, when the two parts of .the rail are united. 4

The adjacent faces of the parts 13 14 are formed with alternately disposed and interlapping grooves and channels21 22, which interlock when the parts, are united, as illustrated in Fig. 4.

The tongues 13 14 will be provided with spaced apertures 23 24, adapted to register when the parts are united andprovide means forthe transverse tie-bolts 25, as shown.

' The tongue members 13 14 are extended vertically downward, and the portions of the tie-flange 12 opposite-the tongues will likewise be extended downward, :as shown, the adjacent ends of the tie-flanges upon the bodies of the rails being merged into them,

as indicated. By this' means the portions of the rails which form the joint are increased when the tongues 13 14 are interlapped, with the head-flanges 10.10 abutting endwise, and the end of the tongues abutting against their respective shoulders'15,"and the divided tiefiange interlocking alohgthe line 1.8, and the tie-bolts 25 secured in place through the apertures 23 24, a joint of great strength is produced, which willlnot only effectually resist any deflecting strainsfrorn thepassing trains, but will likewise resist any lateral or torsional strains.

' It will be noted by reference to Fig. 4 that the vertical strains are borne entirely by the interlocking head members lO and grooves and channels 21 22 and all shearing strains upon the bolts 25 entirely obviated. It will also be obviousthat by increasing the thick-' in size both laterally and-verticallyyso that i the curved portions 20, are an importantfeature of the invention, as they receive the longitudinal strains and prevent end strains between the parts 10 10.

The apertures 23 24: will be elongated to provide for the necessary expansion and contraction.

The peculiar formation of the ends of the rails herein shown can be easily produced when the rails are manufactured by dropforging, hammering, or by pressure, as may be preferred, so that the expense of the joint constructed in this manner may be much less than with joints constructed with extra clampplates or fish-bars.

The improvement may be applied to any of the various sizes of rails.

The tongues 13 14 may be of any desired length and as many of the apertures 23 24 may be employed as required; but generally four will be suificient, as shown.

As many of the interlapping grooves and channels 21 22 may be employed as required, and the parts may be modified and changed as to proportions and relative sizes of the parts without departing from the principle of the invention or sacrificing any of its advantages. By this arrangement of joint the overlapping portions may be coupled by placing the overlapping portions side by side and then engaging them by bringing the parts together laterally, or the tongues 22 and the channels 21 may be engaged by their opposite ends and the rails united by sliding them together longitudinally, as preferred, or as circumstances may require.

Having thus described the invention, what is claimed is 1. A railway-rail joint consisting of OXGP- lapping tongues corresponding to the vertical Webs and projecting beyond the head-flanges and reverse] y extended laterally, said tongues provided longitudinally with interlapping grooves and channels and having transverse spaced apertures for the reception of the tiebolts, substantially as described.

2. A railway-rail joint consisting of overlapping tongues corresponding to the vertical Webs and projecting beyond the head-flanges and reversely extended laterally, said tongues provided longitudinally with interlapping grooves and channels and having transverse spaced apertures for the reception of the tiebolts, and said rails having lateral exten' sions at the roots of said tongues and forming shoulders to receive the abutting ends of the tongue of the opposite rails, substantially as described.

3. A railway-rail joint consisting of overlapping tongues corresponding to the vertical webs and projecting-beyond the head-flanges and reversel y exten ded'laterally, said tongues provided with longitudinally-disposed interlapping grooves and channels, and the tiefiange of said rails divided centrally opposite said tongues and with their ends reversely curved to form abutting interengaging shoulders, and means for transversely connecting said tongues, substantially as described.

4. A railway-rail joint consisting of overlapping tongues corresponding to the vertical webs and'projecting beyond the head-flanges and reversely extended laterally,said tongues provided longitudinally with interlapping grooves and channels, and the tie-flanges of said rails extended vertically and divided centrally opposite said tongues, whereby the sizes of the rails are increased opposite said tongues, and means provided for transversely connecting said tongues, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
